Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
175 words
A universal mounting plate assembly for dental articulators, comprising: a generally flat plate having a central opening therethrough adapted to receive one end of a bolt for securing said plate in place on an articulator frame, one side of said plate having a plurality of recesses adapted to receive corresponding dowel pins for securing said plate upon the frame in non-rotating relationship to said bolt, said bolt projecting into said opening from said one side of said plate, the other side of said plate having a circumferential recess surrounding said central opening, the wall of said recess having a polygonal configuration; and an insert member having an external polygonal configuration conforming substantially to the polygonal configuration of said recess, said insert member being tightly but removably secured within said recess of said plate, said insert member having a threaded opening which is of smaller diameter than said central opening of said plate whereby said insert member is held in non-rotatable engagement with said recess so that said bolt may be threaded into said insert member.
Claim 2
Dependent Claim
175 words
A universal mounting plate assembly for dental articulators, comprising: a generally flat plate having a central opening therethrough adapted to receive one end of a bolt for securing said plate in place on an articulator frame, one side of said plate having a plurality of recesses adapted to receive corresponding dowel pins for securing said plate upon the frame in non-rotating relationship to said bolt, said bolt projecting into said opening from said one side of said plate, the other side of said plate having a circumferential recess surrounding said central opening, the wall of said recess having a polygonal configuration; and an insert member having an external polygonal configuration conforming substantially to the polygonal configuration of said recess, said insert member being tightly but removably secured within said recess of said plate, said insert member having a threaded opening which is of smaller diameter than said central opening of said plate whereby said insert member is held in non-rotatable engagement with said recess so that said bolt may be threaded into said insert member.
Claim 3
Dependent Claim
14 words
The mounting plate of claim 1 wherein said insert member is a hexagonal nut.
Claim 4
Dependent Claim
23 words
The mounting plate of claim 1 wherein said plate is integrally formed of rigid plastic material and said insert is made of metal.
Claim 5
Dependent Claim
16 words
The mounting plate of claim 3 wherein said plastic plate includes silicone as an ingredient thereof.
Claim 6
Dependent Claim
16 words
The mounting plate of claim 1 wherein said flat plate is truncated on one side thereof.
Claim 7
Dependent Claim
169 words
A universal mounting plate assembly for dental articulators, comprising: a generally flat circular plate having a central opening adapted to receive the upper end of a bolt for securing said plate in place on an articulator frame, the lower side of said plate having a plurality of recesses adapted to receive corresponding dowel pins for securing said plate upon the frame in non-rotating relationship to said bolt, the upper side of said plate having a circumferential recess surrounding said central opening, the wall of said recess having a polygonal configuration; and an insert member having an external polygonal configuration adapted to be tightly secured within said recess of said plate, said insert member having a threaded opening which is of smaller diameter than said central opening of said plate for receiving the upper end of said bolt; wherein said circumferential recess is slightly narrowed at the top so that said insert may be press-fitted into place and is then securely retained to enable said bolt to be threaded therein.
Claim 8
Dependent Claim
169 words
